People have been asking this since the program started, and BoI has been very clear that the figure is for gross income. Which makes sense, since otherwise a person paying for insurance or tax by payroll deduction would be treated quite differently from someone paying those expenses separately, even though the two situations are actually identical.
Why? 1) All of my income, savings, and investments are in the US and are denominated in USD, and it would make zero sense to liquidate everything and move it to Thailand. 2) My pension can only be paid into a US bank account. 3) US banks have better consumer protections and interest rates than Thai banks, and will issue credit cards (that have real fraud protection).
We can disagree about the quality and cost of Thai insurance, and agree that medical care here is much cheaper than in the US, but it isn't correct that you "have to pay Medicare" if you have a US address. Part A is free wherever you live, and Part B - which does cost money - is optional wherever you live. You simply decline it, and you pay nothing.
Yes, I have a Thai bank account for day-to-day spending, but that is by no means a solution to all of my banking and financial needs.
That's correct, but the only person whose signature they could notarize would be the OP's, on a self-serving affidavit - which would prove nothing about the genuineness of the documents.
I can't imagine what kind of stamp the UK embassy could put on any of those papers - they certainly don't know anything about your company or your job...
I'll defer to you for receipts from Sisaket. Every receipt I've gotten in Bangkok (Chaeng Watthana and Chamchuri) has been exactly the same blue form, and that seems to be the experience of others posting here as well. If other colors are used in some provinces, I apologize.
